一种基于指纹特征比特串的可撤销指纹加密方案
A cancellable fingerprint bio-cryptosystem based on fingerprint binary string
摘要
Abstract
The cancellable fingerprint bio-cryptosystems based on the fingerprint binary string is study under the premise of protecting the security of fingerprint privacy.During the registration,first detect the fingerprint singular point as the base point,and extract the binary string from the fingerprint as the fingerprint feature,then generate the fingerprint key and auxiliary information by combining the errorcorrect code and fuzzy scheme.Finally,during the authentication,the fingerprint key could be recovered by auxiliary information and homology fingerprint.Experiments demonstrate that the proposed biometric cryptosystem has good recognition performance.And security analysis indicates that the security strength of the proposed biometric cryptosystem can satisfy the need of current security circumstances.关键词
